The strengths of zirconia-to-zirconia joints formed by galsses with diopside (Diop), and eutectic diopside and anorthite (Diop-An) compositions were measured by a shear strength method. The concentration distributions of several elements in the vicinity of the joint interface were observed by SEM and EPMA. When the Diop glass was used as the insert material, the optimum joining temperature was around 1350℃ and the maximum joint strength was 22 MPa. When the Diop-An glass was used, the optimum joining temperature decreased to around 1275℃ and the maximum joint strength was 73 MPa. A modified layer in the insert material was observed in the zirconia adjacent to the joint interface. For the Diop-An glass, the insert layer was amorphous and no crack was not observed in the zirconia, the modified layer, the insert layer or at the joint interface.
